[0002] Overhead transmission lines, especially the ground wires of ultra-high voltage lines, are thin in diameter, usually about 1-2 cm. With the vast sky as the background, it is difficult for birds to quickly detect these thin wires during high-speed flight, resulting in frequent accidents of birds accidentally colliding with transmission lines, causing casualties of rare wild birds such as black-necked cranes, swans, and grey cranes. This phenomenon has attracted great attention from relevant departments. In order to address this issue, scientific research institutions have actively carried out research and application of bird protection warning devices.

It should be noted that the mobile device can drive the clamp through the support frame 2; the support frame 2 is any structure that can stably support the clamp, and its shape and size are designed according to the specific requirements of the clamp and the mobile device. In this embodiment, preferably, the mounting frame is provided with two horizontal and parallel mounting rods, and the ends of the mounting rods are provided with spherical protrusions, and the mounting rods are used to connect the mounting groove 149. In this way, it can provide additional support and stability for the clamp, and serve as a bridge to connect the mobile device, and the clamp can be automatically installed through the mobile device to reduce the danger of manual installation.

[0042] Therefore, the automatic installation fixture for overhead power transmission lines of the present invention solves the technical problems of the prior art such as complicated installation process, low manual installation efficiency and high risk, and achieves beneficial effects: 1) through the ingenious design of the trigger 13 and the card slot 121, when the trigger 13 abuts against the card slot 121, the installation portion remains open, and when the overhead power transmission line contacts the trigger 13, the trigger 13 automatically rotates and disengages from the card slot 121, so that the installation portion closes and clamps the power transmission line, reducing manual operation, realizing the automation of the installation process, and improving work efficiency; 2) the clamping mechanism 1 is composed of a first clamping arm assembly 11 and a second clamping arm 12 connected by rotation, so that the installation portion can be flexibly opened and closed and adapted to power transmission lines of different diameters and shapes, and at the same time, the trigger 13 The long strip or Y-shaped design and the setting of the avoidance groove can extend the force arm and effectively avoid interference with the second clamping arm 12, ensuring the smooth operation of the mechanism; 3) The use of the second protrusion 148 not only enhances the structural strength of the clamp, but also allows manual labor to easily pry open the installation part when necessary, which is convenient for maintenance of the clamp or replacement of power transmission lines; 4) The clamp is also provided with a support frame 2 and a mounting groove 149, which is convenient for connection with mobile equipment (such as drones, robots, etc.) to achieve automatic installation operations at high altitudes or in complex environments, expand the application scenarios of the clamp, and improve its adaptability and flexibility; 5) The design of the entire clamp takes into account safety during operation, and reduces human errors and accidents through automatic opening and closing and firm clamping.

[0043] A second aspect of the present invention provides an installation method for an automatic installation fixture for an overhead power transmission line, which is described in detail below.

[0044] A method for installing an automatic installation fixture for an overhead power transmission line, applied to the automatic installation fixture for an overhead power transmission line provided by any of the above embodiments, comprises the following steps: Pre-adjusting the position of the mounting portion so that the opening of the mounting portion faces downward; The first clamp arm assembly 11 and the second clamp arm 12 are rotated to open the mounting portion, and the trigger 13 is automatically rotated and falls to abut against the clamping slot 121, and the mounting portion remains in an open state; The side of the trigger 13 close to the opening of the mounting portion is brought into contact with the overhead power line, the trigger 13 rotates and disengages from the slot 121, and the fastening assembly drives the mounting portion to close, so that the mounting portion clamps the overhead power line.

[0045] It should be noted that the first clamp arm assembly 11 and the second clamp arm 12 can be opened manually; the installation can be performed manually or by a mobile device (such as a drone, etc.). Preferably, in this embodiment, a drone is used to align the opened installation port of the installation portion with the overhead transmission line and drive the entire clamp to move from bottom to top, so that the trigger 13 of the overhead transmission line is clamped by the clamp.

[0046] Therefore, the installation method of the automatic installation fixture for overhead power transmission lines of the present invention solves the technical problems of the prior art such as complicated installation process, low efficiency of manual installation, high risk, etc., and achieves beneficial effects: 1) Through clear step-by-step guidance, it is simple and clear, and does not require complicated operating skills or additional tools, so that operators can easily master and use the installation fixture; 2) During the installation process, the automation control is high, which reduces the need for manual intervention and improves installation efficiency and accuracy; 3) Since most of the actions in the installation process are completed automatically, the chance of direct contact between the operator and the high-voltage transmission line is reduced, and the risk of electric shock and accidental injury is reduced. At the same time, the clamping force when the installation part is closed is provided by the fastening assembly, ensuring the stability and safety of the clamping; 4) Since the installation process is simplified and the degree of automation is high, the requirements for operator skills and training costs can be reduced. At the same time, rework and losses caused by human errors are reduced, further reducing the overall cost.

[0047] like Figure 1-9 As shown, an optional working process of the installation method of the automatic installation fixture for overhead power transmission lines in the present invention is as follows: In the initial state, under the action of the first spring, the second spring, the first shaft pin and the second shaft pin, the mounting portion formed by the first clamp arm assembly 11 and the second clamp arm 12 is closed; The mounting portion is inverted in advance so that the mounting portion opens downward, and the left and right hands simultaneously pull the second protrusions 148 on the first clamp arm assembly 11 and the second clamp arm 12 to open the mounting portion, and the trigger 13 naturally rotates and falls into the clamping slot 121 under the action of gravity, and the hands are released, and the trigger 13 abuts against the clamping slot 121, so that the mounting portion formed by the first clamp arm assembly 11 and the second clamp arm 12 remains in an open state; The support frame 2 is installed on the drone, and the mounting part is installed on the support frame 2 through the mounting slot 149. The drone is controlled to drive the mounting part to reach below the overhead cable and align the opening of the mounting part with the overhead power transmission line. The drone moves upward to drive the mounting part upward so that the overhead power transmission line enters the mounting part. When the trigger 13 moves upward until the trigger 13 abuts against the overhead power transmission line, the trigger 13 rotates through the second rotating shaft 17 and disengages from the slot 121. The first spring and the second spring pull the first clamp arm assembly 11 and the second clamp arm 12 to close the mounting part. The mounting part clamps the overhead power transmission line to complete the automatic installation.
